T cell whom it may concern; v,

Beit known that we, ROBERT C. RUSSELL and ANDREW W. SIEGEL, citizens ofthe United States, residingat W'i'lliamsport, in the county of Lycomingand State of Pennsylvania, have invented a new and usefulCarpet-Fastener,

of which the following is a specification.

This invention relates to carpet-fasteners, and especially to a fastenerfor securing carpets upon stairs, and has for its objects to produce asimple inexpensive device of this character susceptible of readyapplication'or removal and one which will in practice maintain thecarpet securely in position.

To these ends the' invention comprises the novel features ofconstruction and combination of parts more fully hereinafter described.

I In the accompanying drawings, Figure 1 is a perspective viewillustrating one form of embodiment of the invention applied. Fig, 2 isa similar view of one of the members of the fastener. Fig. 3 is asimilar view of the other member of the fastener. Fig. 4 is a sectionalelevation showing another form of embodiment of the invention. Fig. 5 isa similar view disclosing still another form.

Referring to the drawings, 1 designates the tread, and 2 the riser, of astair, these parts being of the usual or any preferred construction, and3 a section of carpet secured to the stair by my improved fasteningdevice 4, which, as herein shown, consists of a primary engaging memberor base-plate 5 and a secondary clamping or retaining member 6.

As illustrated in Figs. 1, 2, and 3, the primary member 5 is in the formof a sheetmetal plate having a central longitudinallydisposed channel ordepression 7, thus producing upon the normally rear or inner face of theplate a rib or projection 8,which terminates short of one end of theplate, as atv 9, and produces in rear of the plate, when in positionupon the stair, longitudinal recesses 9'. The plate is provided at itscenter with openings or perforations 10, which receive screws oranalogous fastening devices 11, by which the plate is secured to thestairriser, while upon the longitudinal edges of the plate there isSerial Fo.'l79,059-. (No model.)

of a suitable length i of sheet metal folded back upon itself to form anouter bearing plate or. portion 13 and an inner plate or portion whichis centrally re-- cessed orcut away, as at 14, to produce a pair ofspacedengaging arms or elements 15, disposed in parallel relation anddesigned in practice to enter, respectively, the recesses 9, with therib or projection 8 between them, and to bear at opposite sides of thelatter on the rear face of member 5. It is here to be noted that theouter plate 13 is of a transverse width slightly less than the distancebetween the teeth 12 on opposite sides of plate 5, whereby when theparts are assembled the edges of the plate will lie just within the lineof the teeth, thereby pressing the carpet into direct and secureengagement with the latter, and, further, that when the member 6 ismovedto position upon the member 5 it will be limited or stopped in suchmovement by the end 90f rib 8 with which it will come in contact. InFig. 4 the members of the device are identical with those abovedescribed, except that the base-plate 5 is angularly bent at itstransverse center into L form in cross section, whereby it will fitsnugly into the angle or corner at the juncture of thetread and riserand that the outer plate 13 of the member 6 is given a transverse inwardcurvature or bend for nearer approach to the base-plate.

In Fig. 5 the outer plate 13 of member 6 has along its longitudinaledges inner grooves or recesses 16, which overlie the teeth or prongs 12and produce inwardly-extending edge flanges 17, designed to bear uponthe carpet transversely beyond said teeth, the parts being otherwiseidentical in construction and operation with that above described.

From the foregoing'it is apparent that in order to secure the carpet inposition the member 5 is attached to the stair,- the carpet laid overand pressed downward upon the teeth 12, and the member 6 slipped by anendwise movement into position with its plate 13 overlying the carpetand its arms or elements 15 engagwith a base-plate adapted forattachment to a.

* stair, of a clamping-plate adapted for cooperation with the base-plateto hold a carpet disposed between them, and an arm provided on one ofsaid plates to engage the outer face of the other.

2. In a carpet fastener, the combination with a base-plate adapted forattachment to a stair, of a clamping-plate adapted for cooperation withthe base-plate to hold a carpet disposed between them, one of saidplates being provided with a recess and the other with an engaging armdesigned to enter the recess.

3. In a carpet fastener, the combination with a base-plate adapted forattachment. to a stair'and having a rear recess, of a clamping memberadapted for cooperation with the baseplate to hold a carpet disposedbetween them, said member having an engaging element adapted forentering the rear recess to hold the parts in clamping position.

4:. In a carpet fastener, the combination with a base-plate adapted forattachment to a stair and having a longitudinal rib disposed between itstransverse edges, of a clamping member adapted for engagement with thebase-plate for holding a carpet disposed between them, said memberhaving engaging elemgnts adapted to lie upon opposite sides of the r1 5.In a carpet-fastener, the combination with a base-plate adapted forattachment to a stair and having a longitudinal rib disposed between itstransverse edges, of carpet-engaging teeth or prongs provided upon theedges of the base-plate, and a carpet-engaging member cooperating withthe base-plate to hold a carpet disposed between them, said membercomprising an outer plate and a pair of inner spaced arms adaptedtoengage inrear of. the base-plate and receive the rib between them.

In testimony that we claim the foregoing as our own we have heretoaflixed our signatures in the presence of two witnesses. 1
